Typically engine Manufacturers specify 10W-30 lubricants down to around -15F and 5W-30 lubricants to around -22F. These are continuous temps so spasmodically below a little won't be an issue. As others have alluded to though it may "test" the battery and starter a bit!

10w30,耐低温-25,有车库问题不大,没车库停放10个小时就不好说了,启动困难会损坏电瓶寿命。应该用5W或者0W才能在-30或-35度保持机油的低温流动性,利于启动和低温保护。
